Notes on the Cluster Gutzwiller Method: Inhomogeneous Lattices, Excitations, and Cluster Time Evolution
arXiv:1608.02905
Abstract
Several perspectives of the cluster Gutzwiller method are briefly discussed. I show that the cluster mean-field method can be used for large inhomogeneous lattices, for computing local excitations, and for the time evolution of correlated quantum systems.
